The typical pursuant of the Holy Knight class is a paladin. This is because of the requirement of being able to cast paladin spells. The class is what to pick if your party needs a little more spellcasting support. The most important ability score is wisdom. Wisdom decides what level spells you can cast, and how hard they are to resist. After that, typical combat, constitution to stay alive, strength for damage dealin, and a little dexterity goes a long way in avoiding being hit.

Spellcasting: Levels of Holy Knight stack with levels of paladin for the purposes of determining smite damage, lay on hands, and special mount.

Spellcasting: At each level, you gain new spells per day and an increase in caster level (and spells known, if applicable) as if you had also gained a level in the paladin spellcasting class to which you belonged before adding the prestige class level. You do not, however, gain any other benefit a character of that class would have gained. If you had more than one paladin spellcasting class before becoming a Holy Knight, you must decide to which class to add each level for the purpose of determining spells per day, caster level, and spells known.

Deity, Domains, and Spells: A Holy Knight chooses one domain at first level and chooses another at 3rd level, if he follows a deity, the chosen domain must be a domain in the deities portfolio; He can always choose the War, Strength, Good, and Law domains, even if he doesn't have a deity, or they aren't part of his deity's domains. He can prepare one spell in each of your Domain slots each level as shown above. He prepares spells each day at a specific time which he chooses on entering the class. He uses his wisdom to determine the save DC of spells (10+paladin level + Holy Knight lvl+Wisdom modifier), and what spells he can cast. He must have a wisdom score of at least 10 + the spell's level to cast a Holy knight spell. Holy Knights do not gain bonus spells because they do not have spell slots, they have only domain spell slots. With access to two domain spells each spell level at 3rd level, a Holy Knight prepares one or the other each day in his domain spell slot.

Resourceful Secret (Ex): At second level, a Holy Knight chooses a spell of 2nd level or lower from the sorcerer/wizard spell list and gains the ability to cast it as a spell-like ability (Sp) once per day, as a caster of his Hit Die.

Work of Dedication (Ex): At fourth level, a Holy Knight chooses a spell of 4th level or lower from the sorcerer/wizard spell list and gains the ability to cast it as a spell-like ability (Sp) once per day, as a caster of his Hit Die.

Wild Reflection (Su): At fifth level, a Holy Knight chooses a spell of 4th level or lower from the druid spell list and adds it to the list of class spells for his paladin casting ability.

Combat: A Holy Knight is a paladin with more spellcasting abilities. The role in combat is the same, but you have a few more options for big fights. Fight on the front line and protect the other spellcaster(s) in the party. If a situation needs one of your domain spells use it.

Advancement: The best advancement for a Holy Knight is paladin. The spellcasting isn't strong enough to warrant other classes. You could also go fighter for more combat prowess.

Resources: Holy Knights are part of church organizations. They can expect to receive a small amount of help if their cause is viewed as just by the church leaders.
